I found almost all the things that made my cars performance suffer. Whats have you guys found that was wrong and the exact cure to fix it? My example was a broken rear exhaust manifold bolt so i bought headers and fixed that problem. I read so many threads where the problem was addressed but no one followed up to say what there results were after our advise.

 

needed egr valve.. so i ripped out everything emissions related.

collapsed lifter- put in cam,lifters,springs roller rockers

needed opti- ended up doing a full msd igniton

driveshaft vibrated- installed aluminum one

ac stopped working- tore it out

im sure theres 100 more for me.. haha the list would go on and on

 

My car had a miss
Replaced-ngk plugs, msd wires, msd coil, turns out it was a dirty air filter, Cold air intake.

 

Motor would not start after cam install. Reason found to be opti installed wrong, (cam pin jammed in wrong slot).

Rocker came loose, valve slapped the piston.

Solution? Replace entire motor with nastier 355

 

Burned plug wire = MSD cap and rotor, new opti, MSD 6AL, MSD wires
Bad ignition module = new fuel pump, new FPR, and finally new module

 

My a/c wasn't working and it ended up being a 40 dollar high pressure sensor on the a/c line. Caused my fans to run all the time and prevented the a/c clutch from engaging.

 

Something's wrong with my Z-28 and I've tried all kinds of things to fix it. I think I'm just going to light it on fire. That'll take care of it.

 

Mine was skipping past 5000 rpm after plugs and wires. I had installed bosch plattunms and regapped. then on here I read not to gap platunms. got autolite 104 at .030 no skip or miss

 

leaking fuel injector caused this


replaced it with this (and everything in sig at once)

 

PROB: hard starting
FIX: fuel pressure regulator was bad, replacing it fixed it

PROB: ticking noise from transmission/rear of engine area
FIX: broken flexplate, replaced it and was good

PROB: fans did not turn on at all
FIX: manual fan switch installed, turned on at all times

 

My car ran like crap when it was cold and when i replaced the temp sensor it made all the difference in the world.

 

Problem: From the factory our cars have highly restrictive inductions
Solution: Replaced with K&N FIPK2, now get on average 3-4 mpg better fuel economy

Problem: Lost 2nd gear, skip shift was a PITA
Solution: rebuilt T-56 with stronger syncros, added SLP skip-shift delete, brand new clutch w/ new slave cylinder. Currently running 10k miles on rebuild.

 

I have a 94 lt1 Formula

Problem was overheating

sulution was = Make sure overflow tank is connected to top connecter on radiator, not the second one down. If you rev your motor up and the temp drops, this is more than likely the problem.

 

my car would run fine till it got up to normal driving temp the it would start to miss at about 3k rpms and surge at idle.

found a broke bolt where the iac valve mounts to the throttle body
